Explore the periodic table interactively with MatterChart. Discover element properties, visualizations, and their compositions. Perfect for students, educators, and enthusiasts.
The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one,...

They are either being incredibly honest, or they really don't understand what they're saying when they list what amounts to nearly the entire periodic table on the label, as the "trace minerals" they contain. Here is the list in all its glory, typed in by my daughter in exchange for...

The Red Green and Blue company in England sells a very nice element collection in several versions.Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table. To learn more about the set you can visitmy page about element collectingfor a general...
One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity orperiodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into meta...
